The Klein Four (A group)
Perhaps The Klein Four have passed you by as well as me. Well fret not. They are an a capella group from the maths department of Northwestern Univeristy and they shot to fame last year with their love song Finite Simple Group of Order Two, which can be watched online:
They have an album out, full of more maths puns than you can shake a stick log at, which you can purchase via their website (where you can see some of their other performances) or even via iTunes.
The Klein four group, or Vierergruppe, is a direct product of two copies of Z_2, and allows us to solve the quartic.
